    Okay so I have a predator installed on my truck and my truck is due for smog testing am I going to have any problems when I take it in? because I was thinking should it create less emissions since the programmer helps with MPG?

    Does your predator have a CARB certificate?
    If it does you should be ok, put the settings back to stock before going to the test site.
    If you dont have the CARB cert. make sure theres no sign of it being used on the truck.

    i have no experience with smog & tunes, but all of the custom tuners I've talked to say "if It'll pass without the tune, then it'll pass with it".
